Do you have a recommendation for when to use EmbeddedMetadataMode?

The default seems to be False but in the SBDataStorage unit there's a comment that refers to "Legacy Mode" is where data is stored apart from the object data.

For new S3 buckets, would you always recommend switching from the default to True for EmbeddedMetadataMode?

Hi Darian,

In the embedded metadata mode all objects store their security settings within themselves, and not in separate metadata objects. This gives some nice benefits with regard to speed- and transaction-related capabilities of your application, but may cause interoperability issues if you need to work with the same objects with some third-party SDK.

Generally, the use of embedded mode is justified when you access your objects solely with your application (i.e. without any third-party Cloud components or tools). We recommend using it for all new such applications. The default value of false was chosen to preserve backward compatibility with older SecureBlackbox versions (where there was no embedded mode available), as quiet change of the mode for existing applications would have broken them.

As you are going to create new S3 buckets, switching EmbeddedMetadataMode to true might make good sense for you.

That's what I assumed, but wanted to get confirmation. Thanks!
